Guy,s I do not have Red-e-set, but Grid-lok offers a fully automatic system that easily installs onto the printers and P&P. It can be set to your board instantly by pressing one button or triggered by the printer to set for each consecutive PCB. They

have you tried a more agressive flux like water soluble to see if the problem goes away? Or can they be hand soldered with no problem? I am basically out of ideas other than a bad nickel or tin finish. The reflow profile didn't seem out of whack f

You could also try using a wire mesh out of stainless steel(won't rust). We used these as reflow baskets and for covering parts for a steam cleaner we had for W/S flux. go to http://www.mcmaster.com and type in *Metal and Thermoplastic Cloth and Perf

Echoing SheanDalton's comments [above in this thread]: * A good way to strip part markings, solder mask, etc. * A fairly aggressive against most polymers. * A flammable material. * VOC issues in its use. * Assembly workers don't like the smell. * A

Tried with several lots of solder paste, manufactured in Feb and March this year. Work ambient: 25C, 60~70%. Is this humidity too much? I'll reduce the ramp in our profile. One change: We changed the conveyor motor in our reflow oven just before the

I know your frustration. CP6 feeders are notorious for this issue. They have always been an issue. You have probably went through the "change spring, change tape leaf, change component reel, place peeler tape over two rollers instead of three" scenar

Hi Dave, 3M� Spray 75 Repositionable 500 ml was the last we used due to a bright spark in purchasing, but production didn't get on with it too well. The only one that really gives us good consistant performance was the original 400ml Spraymount a

Hello Everyone, We are having some problem with Palladium-Silver surface finish. We have ceramic components with the above surface finish. When we try to assemble these on Sn/Pb solder, we are observing open joints. If we reflow the compt for more t

Hello, I have been tasked with updating our PCB cleaning sytem, of which I know little about, and could really use some advice. We are a small company and we hand solder our electronics to IPC standards. Our electronics are mission critial communic

Thanks for the input guys. One problem with this theory, we see the same failure using Omni 5000 solder paste. We also see this problem across 4 production lines, suggesting it is not oven related. The profile meets recomendations and we have tried
